TECHNICAL FIELD

Aspects of the disclosure generally relate to systems and methods forgrow light systems, and more particularly to systems and methods for LEDgrow light systems for growing plants.

BACKGROUND

Grow lights are used for horticulture, indoor gardening, hydroponics andmany other uses both at the industrial level and at the personalhousehold level. Many types of light bulbs can be used with grow lights,but typically, grow lights use incandescent bulbs, florescent lights,high-intensity discharge lamps, high-pressure sodium (HPS/SON) and metalhalide (MH) HID lights. While these lights are effective for growingsystems, many disadvantages of these systems exist. For example, many ofthese lighting systems are inefficient in that much of the energy usedto power the systems cannot be effectively converted to light energyand/or the wavelengths of light produced by these lighting systems doesnot efficiently contribute to plant growth. Additionally, many typicalgrow light systems emit too much heat which can cause plants totranspire more and as a result increase the amount of water needed togrow the plants.

Recently LED (light emitting diode) technology has been used for growlight systems. LED grow light systems offer many advantages to typicalgrow light systems in terms of efficiency. For example, LED systems aremore efficient than typical grow light systems at converting electricalenergy to light energy necessary for plant growth. Additionally, LEDgrow light systems can utilize the particular wavelengths necessary forplant growth. For example blue light (455 nm-470 nm) can be used topromote vegetative or leaf growth, and red light (620 nam-665 nm) can beused to promote plant flowering. LEDs can also operate at lowertemperatures than some typical lighting systems.

While LED lighting systems offer many advantages over typical grow lightsystems, many disadvantages still exist. A LED grow light system thatovercomes the deficiencies of current systems is desired.

A grow light system 100 according to aspects of this disclosure is shownin FIG. 1. As shown in FIG. 1, the grow light system 100 can have ahousing 101 having a generally rectangular box shape including a frontside 102, a back side 104 (not shown), a top side 106, a bottom side(not shown) and two sidewalls 110. Although the housing 101 shown inFIG. 1 is a rectangular box shape, any other suitable housing shapes canbe used, such as, a pyramid shape, triangular prism shape, and cylindershape. The grow light system 100 can also include a user interface 112,and a cooling fan 114. The grow light can also include a power switch116, a power supply port 118, and as will be described in more detailbelow, a number of input/output ports 120, 122. The housing 101 can beabout 16 inches long or in the range of about 12 inches to about 20inches, about 7.5 inches high or in the range of about 5 inches to about10 inches, and about 10 inches deep or in the range of about 7 inches toabout 13 inches. Thus, the housing can define an internal volume of, forexample, about 1200 in³ or in the range of about 420 in³ to about 2600in³.

As shown in FIG. 1, the grow light system 100 is designed to hang or beplaced above a light dependent organism, such as a plant, such that theLEDs engaged with the bottom surface can shine down on a plant. Thus,the grow light system 100 can include any device 123 capable of holdingthe system 100 above a plant, such as chains as shown in FIG. 1.

As shown in FIG. 2-FIG. 2C, the grow light system also includes at leastone LED module 200. The LED module 200 includes a circuit panel 202. Thecircuit panel 202, can be manufactured using any known methods. Thecircuit panel 202 can include electrical connectors 204, which as willbe discussed in more detail below, connect to a carrier board to supplypower to the LED module 200.

The LED module 200 also includes a plurality of LEDs 206 electricallyconnected to the panel 202. As shown in FIG. 2-FIG. 2C, seven LEDs areshown attached to the panel 202 of the LED module 200, however, anynumber of LEDs 206 can be used on the panel 202. For example, in someembodiments, the panel 202 can include in the range of 3 to 10 LEDs 206.The LED 206 on any particular module 206 can be similar to each other orcan be of different brightness (lumens, PAR, etc.), wavelength, andillumination angle to allow the LED module 206 to be customized andadapted easily for multiple different applications or methods.

Each module 200 can include different combinations of LEDs 206 havingthe same or different wavelengths. As is known in the art, thewavelength of the LED 206 determines the color of the LED 206. Forexample, red LEDs can have a wavelength of about 620 nm-625 nm, dark redLEDS can have a wavelength of about 660 nm-665 nm, red-orange LEDS canhave a wave length of about 610 nm-620 nm, green LEDs can have awavelength of about 520 nm-550 nm, cyan LEDS can have a wavelength ofabout 490 nm-520 nm, blue LEDs can have a wavelength of about 465 nm-470nm, dark blue LEDs can have a wavelength of about 455 nm-460 nm, warmwhite light LEDs can have more red wavelengths and are rated in colortemperatures of about 2,000-4,000 K, and cool white light LEDs can havemore blue wavelengths are rated in color temperatures of about5,000-10,000K.

In some embodiments, each of the LEDS 206 on an LED module 200 can be ofabout the same wavelength. In other embodiments, the LEDs 206 on a LEDmodule 200 can vary. For example, some LED modules 200 can include LEDshaving a ranging of wavelengths from about 400 nm to about 700 nm.

In some embodiments, each of the LED modules 200 on a particular growlight system 100 can have similar layouts of LEDs 206. As shown, forexample, in FIG. 2A each LED 206 can have a certain location 206A, 206B,206C, 206D, 206E, 206F, 206G. Thus, in a particular grow light system,each of the LED modules 200 can have a similar LED in the 206A location,a similar LED in the 206B location, a similar LED in the 206C location,a similar LED in the 206D location, a similar LED in the 206E location,a similar LED in the 206F location, and a similar LED in the 206Glocation. In another example, a row of LEDs 206 (for example 206A, 206B,206C) on each LED module 200 could be red LEDs and another row (forexample 206D, 206E, 206F, and 206G) could be all green LEDs. In thisconfiguration, an operator could turn off the red LEDs and turn on thegreen LEDs when operators will be working on the light dependentorganisms, such as plants, but do not want to encourage photosynthesis.In other embodiments, a system can have a range of only red LEDs thatcould provide higher levels of that wavelength during critical times ofplant growth. During other periods of plant growth these LED modulescould be later replaced with LED modules having other wavelengths, suchas general purpose LED modules with basic colors used by plants.

The LED module 200 also includes a heat sink fin 208. The heat sink fin208 can be generally U-shaped having a first wall 210 that extends awayfrom the panel 202 and can be generally perpendicular to the panel 202,a second wall 212 that extends away from the panel 202 and can begenerally perpendicular to the panel 202, and a third wall 214 that canbe generally parallel with the panel and connects to the first wall 210and to the second wall 212. Although a single heat sink fin 208 is shownin FIG. 2-FIG. 2C the heat sink fin 208 can, for example, comprisemultiple U-shaped fins. Although a U-shaped fin is shown, other heatsink fin shapes can be used. Additionally the heat sink fin can includeother features, such as tabs, holes, or other elements, on the fin thatcan increase heat dissipation.

The size of the heat sink fin 208 can be important to the functionalityof the grow light system 100. The height of the first and second walls210, 212 can be approximately 1.75 inches or in the range of about 1.5inches to about 3 inches. The length of first and second walls 210, 212can be approximately 3 inches or in the range of about 2 inches to about5 inches. The third wall 214 can have a width of about 1 inch or in therange of about 0.5 inches to about 2 inches. Thus, the first and secondwalls 210, 212 can be spaced apart from each other by about 1 inch or inthe range of about 0.5 inches to about 2 inches.

The heat sink fin 208 is a passive heat exchanger configured to cool theLED module 200 by dissipating heat from the panel 202 and the LEDs 206.The heat sink fin 208 can be manufactured of any suitable material. Forexample in some examples the heat sink fin 208 can be manufactured ofaluminum or aluminum alloys, and other materials can include copper,composite materials, and other good heat conducting materials.

The heat sink fin 208 can be removably or permanently attached to thepanel 202 in any suitable manner. As shown in FIG. 2, the heat sink fin208 can be attached to the panel 202 with a nut 218 and bolt 220attachment mechanism at either side of the panel 202. Any other suitableattachment mechanism can be used including the use of adhesives. The LEDmodule 200 can also include a heat conducting element, such as a highlyconformable, low-modulus material such as silicone polymer, positionedbetween the panel 202 and the heat sink fin 208 to facilitate heattransfer between the panel 202 including the LEDs 206 and the heat sink208.

The grow light system 100 can also include a carrier circuit boardassembly or carrier board 300 that can form the bottom side of thehousing 101, can removably engage the LED modules 200, and can containcircuits to electrically connect components engaged with the boardincluding the LED modules 200. The carrier board 300 contains apertures302 for insertion of the LED modules 200. As shown in FIG. 3 (depictingan example mounting plate) and FIG. 4 (depicting an example carrierboard assembly 300), the carrier board assembly 300 can include ninegenerally rectangular apertures 302 to house nine LED modules 200. Insome embodiments the number of apertures 302, and hence the number ofLED modules 200, can vary. For example, in some embodiments, there canbe in the range of about 5 and 12 LED modules. Each aperture 302 canhave a first and second lateral edge 271, 272, and a first and secondlongitudinal edge 273, 274. The carrier board assembly 300 can alsoinclude electrical connectors 304 for interfacing with the electricalconnectors 204 of the LED modules 200 to provide power to the LEDmodules 200.

As shown in FIG. 3, apertures 302 can be defined in the mounting plate299. In an embodiment, the mounting plate 299 includes a front edge 281,a rear edge 282, a right side edge 283, a left side edge 284, and asurface 285 contiguous to and extending between the edges. In anembodiment, the mounting plate 299 can be configured so that it can bepositioned proximate the bottom of the housing 101 to form a bottomsurface of the housing. In an embodiment, the front edge 281 can bepositioned proximate the front side 102 of the housing 101, the rearedge 282 can be positioned proximate the back side 104 of the housing101, and the right and left sides 283, 284 can be positioned proximaterespective sidewalls 110. In an embodiment, the mounting plate isconfigured to direct airflow into the apertures 302 and/or gaps definedbetween the aperture edges 271, 272, 273, 274 and an LED module 200positioned in the aperture 302, as described below, as the fan draws airinto the housing 101. In an embodiment, the apertures 302 form agenerally X-shaped layout which has been found to be very conducive togrowing plants, however the carrier board assembly 300 can be configuredin different sizes and shapes with different layouts of LED modules 200to provide for optimal plant light coverage. The apertures 302, forexample, can be arranged in different patterns such as circular,rectangular, or columns and rows. In another embodiment, the LEDs 206can form a grid pattern. In still other embodiments, the carrier boardassembly 300 could be longer and/or have a thinner width that would beoptimal for placement on a long narrow shelf. The LED modules in such aconfiguration could be placed in rows or other suitable layout.

FIGS. 4-5 show the LED modules 200 installed in the carrier boardassembly 300. The LED modules 200 can connect to the carrier board 300using any type of suitable fastener. As shown in FIG. 5, the fastener306 can be a screw connection, a nut and bolt system, or any othersuitable fastener including adhesive. The carrier board assembly 300 canbe formed of any common materials using standard manufacturingprocesses.

As shown best in FIGS. 4A and 5 the LED modules can be spaced from theface 303 of the carrier board assembly 300. In some embodiments the LEDmodules 200 can be spaced from the face 303 of the carrier board 300using a spacer 308. The spacer can be formed of any material and in someembodiments can be formed of a nonconductive material such as plastic.The spacer can be about 0.25 inches high or in the range 0.125 inches toabout 0.5 inches. In other embodiments, the LED modules can be spacedfrom the face 303 of the carrier board assembly 300 without the use of aspacer.

This space between the face 303 of the carrier board 300 and the back207 of the LED module 200 can define a vertical gap 310. Additionally,as shown at least in FIG. 5, the apertures of the carrier board 202 aresized to be slightly larger than the heat sink fin 208 formingadditional gaps between the carrier board assembly 300 and the heat sink208. For example, in the longitudinal direction, or length of the LEDmodule 200, there can be a longitudinal gap 312 on either side of theheat sink 208 (between the longitudinal edges 273, 274 of the aperture302 and the heat sink 208) of approximately 0.0125 inches or in therange of about 0.00625 inches to about 0.25 inches. Similarly, in thelateral direction, or width of the LED module, there can be a lateralgap 314 on either side of the heat sink 208 (between the lateral edges271, 272 of the aperture 302 and the heat sink 208) of approximately0.00625 inches or in the range of about 0.003125 inches to about 0.25inches.

Although LEDs can reduce the temperature of a grow light system, LEDs206 can still cause the temperature of the grow light system 100 toexceed preferred operational levels which can decrease the life of theLED. The gaps 310, 312, and 314 along with the heat sink fin 208 canreduce the temperature of at least portions of the grow light system100. As described above, the grow light system 100 includes a coolingfan 114. The cooling fan 114 is configured to draw ambient air fromoutside of the grow light system into the housing 101 through the gaps312, 314, and 316 which can cause a negative pressure inside the housing101. The fan can then blow the air out the top side 106 of the housing101. More specifically, each of the vertical gap 310, longitudinal gaps312, and lateral gaps 314, are configured such that air can be drawn bythe cooling fan 314 over the face of the LEDs 206 on the panel 202,through the gaps, 310, 312, and 314 and along the fin 208. The coolingfan 114 can be any fan suitable to reduce the temperature of the LEDmodules 200. In some examples, the fan can be sized to move a lot of airproviding a greater cooling effect, however, this can increase the noiseproduced by the system. In other embodiments, the fan 114 can run atlower speeds providing less cooling but less noise as well. Fans, heatsinks, and gaps in carrier can be sized appropriately to provide optimumcooling with the least amount of side effects, such as noise andinternal temperature rise.

Referring now to FIG. 6 which shows a circuit diagram representing thegrow light system 100. The grow light system includes a power supply 602for providing power to the grow light system and includes a master CPU604 for controlling the grow light system 100. The grow light system 100can also include LED Drivers 606 to control the LED circuits. Asdescribed above, each LED module 200 can include a plurality of LEDs 206(represented as D1 (206A), D2 (206B), D3 (206C), D4 (206D), D5 (206E),D6 (206F), and D7 (206G) in FIG. 6). As shown in FIG. 6, each LED 206corresponding to the same location on a particular LED module 200 can bewired in series with the other corresponding LEDs 206 of the other LEDmodules 200. In other embodiments, LEDs having the same wavelength,color, or a number of other variables can be wired in series together.For example, as shown in FIG. 6, each of the LEDs 206 represented as D1(206A) can be wired in series with each other, each of the LEDs 206represented as D2 (206B) can be wired in series with each other, each ofthe LEDs 206 represented as D3 (206C) can be wired in series with eachother, each of the LEDs 206 represented as D4 (206D) can be wired inseries with each other, each of the LEDs 206 represented as D5 (206E)can be wired in series with each other, each of the LEDs 206 representedas D6 (206F) can be wired in series with each other, and each of theLEDs 206 represented as D7 (206G) can be wired in series with eachother. For example, in some embodiments, all LEDs 206 represented as D1may be blue LEDs (455 nm-470 nm) and all LEDs 206 represented as D2 maybe red LEDs (620 nm-665 nm). Additionally, as shown in FIG. 6, each ofthe LEDs 206 represented by D1 (206A) are connected to a single LEDdriver 606, each of the LEDs represented by D2 (206B) are connected to adifferent LED driver 606, and so on. Wiring the LEDs in series in thismanner can provide significant advantages to a user. As will bediscussed in more detail below, this allows a user to vary the intensityof each of the D1 (206A), D2 (206B), D3 (206C), D4 (206D), D5 (206E), D6(206F), and D7 (206G) LEDs independently. Thus, for example, a usercould increase the intensity of the D1 LEDs (206A) and/or decrease theintensity of the D2 LEDs (206B). Additionally, as will be discussedbelow, if, for example, a D1 LED failed the user could quickly identifythat one of the D1 LEDs must be replaced.

As shown in FIG. 6, in addition to wiring the LEDs 206 of the grow lightsystem 100 in series, the grow light system 100 can include one LEDmodule 200 that is not wired in series like the other LED modules 200.This LED module 200 can be the same or similar to the other LED modules200 and it can differ in that it is electrically connected through thecarrier circuit board assembly 300 differently than the other LEDmodules 200. As shown in FIG. 4, the carrier circuit board assembly 300can include one LED module 200 location that can be designated the testlocation 608. This test location 608 as shown in FIG. 6 is not wired inseries like the other LED modules 200 and can allow a user toindividually test a LED module 200 for operability. For example, if oneof the D1 LEDs (206A) stops working on one of the LED modules 206, allof the D1 LEDs (206A) on the LED modules 200, except for the LED module206 in the test location 608, will stop working. This can allow the userto quickly identify which LED location (for example 206A, 206B, 206C,206D, 206E, 206F, or 206G) is not working. The LED module 206 that needsto be replaced can quickly be determined using the test location 608 asa module testing point.

The grow light system 100 can also include a plurality of componentshaving various functions to provide a user interface, system monitoring,control, data collection, and file sharing. The grow light system 100can be used in various applications and is described herein as adaptedfor growing plants as a particularly useful example. In an embodiment,the grow light system 100 can include one or more control processors,growing environment sensors, a real time clock, date and time loggingdevice, executable programs, non-volatile memory, analog signalconverters for inputs and outputs, digital signal generators for inputsand outputs, interface hardware and software for interfacing with othercontrols (such as, for example, RS232, RS485, and similar controls),power supply, audio devices, display with or without touchscreen andwith or without video or slide show capability, Wi-Fi module, localwireless connections (Bluetooth, ZigBee), and USB interface.

As shown in FIG. 7, the grow light system 100 can include a number ofcomponents that can be used to control and optimize the growing ofplants. The grow light system 100 can include one or more processors 702for controlling overall operation of the system and its associatedcomponents, including RAM 703, ROM 705, input/output module 704, memoryunit 706, display and/or user interface 112, Wi-Fi module 705, and a LANinterface 711.

The input/output module 704 can include a, keypad, touch screen, and/orstylus through which a user of the grow light system 100 can provideinput, and may also include one or more of a speaker for providing audioinput/output and a video display device for providing textual,audiovisual and/or graphical output. Additionally, the input/outputmodule can include a number of ports, such as USB port(s) 707 andEthernet port(s) 709 for sending and receiving information.

In embodiments, the grow light system 100, through the I/O module 704,can monitor and control operation of a growing environment. For examplethe I/O module 704 can receive information from a spectral lightevaluation sensor 708 to provide a spectral light evaluation; an airhumidity sensor 710 to determine the humidity of the air in the growingenvironment; an air flow sensor 712 to determine the air flow in thegrowing environment; a soil moisture sensor 714 to determine themoisture of the soil in a growing environment; a pH sensor 716 todetermine the pH of the soil (or other growing medium such as water in ahydroponic environment) in the growing environment; an air sensor 718 todetermine the air composition in the growing environment including forexample carbon dioxide levels and oxygen levels; an ambient airtemperature sensor 720 to determine the air temperature in the growingenvironment; and a video camera 721 to view the growing environment.Additionally, the grow light system 100 can be used in hydroponicapplications, and in such applications additional sensors can beincluded in the grow light system 100. For example, the I/O module 704can receive information from a water flow sensor to determine the waterflow in the hydroponic growing environment 722; and a water level sensor724 to determine the water levels in the hydroponic growing environment.

The I/O module 704 can receive inputs from at least the sensors 708,710, 712, 714, 716, 718, 720, 721, 722, 724. The data from these sensorscan be monitored, and stored or data logged in the memory 706. As willbe discussed in more detail below, based on the data from these sensors,the grow light system 100 can make changes to the growing environmentbased on preset parameters. For example, in some embodiments, water ornutrients could be added to the growing environment based on the datafrom the sensors. In still other embodiments, if any parameters areoutside of certain preset limits, the grow light system could shut downand an alarm could be sent to the operator. In still other embodiments,the grow light can be adapted to adjust light intensity and/or spectrumto optimize growth and/or protect the plants from harm. Additionally thegrow light system 100 can log information from each of the sensors alongwith other information such as date and time information which can beused to build a program for growing a particular type of plant.

As shown in FIG. 7, the I/O module 704 can also receive informationthrough at least the user interface 112, Wi-Fi module 705, LAN interface711, and one or more ports such as a USB port 707 and an Ethernet port709. As will be discussed in more detail below, a user can change anynumber of different growing environment variables from the userinterface 112. The ports 707 and 709 can provide additional informationfrom any number of different sources. The ports can be used, forexample, to network multiple grow light systems 100 together.Additionally, the ports 707, 709 can be used, for example, to downloadcertain growing condition information to the grow light system 100. Forexample, a user could download a program for growing a certain type ofplant, and in some embodiments this program can provide an ideal growingenvironment for that particular type of plant.

Software may be stored within memory unit 706 and/or other storage toprovide instructions to the processor(s) 702 for enabling the grow lightsystem 100 to perform various functions. For example, memory unit 706may store software used by the grow light system 100, an operatingsystem of the grow light system 100, application programs of the growlight system 100, and/or an associated internal or external database(s).The memory unit 706 can include one or more of volatile and/ornon-volatile computer memory to store computer-executable instructions,data, and/or other information.

The processor 706 and its associated components may allow the grow lightsystem 100 to receive information corresponding to a plurality ofoperating information from sensors and devices associated with a growlight system 100 and related devices. As described above, such operatinginformation can include, for example, lighting information, humidityinformation, air flow information, soil moisture information, pHinformation, air composition information, ambient air temperatureinformation, water flow information, and water level information.Additional information can include, for example, date, time and energyconsumption. The processor 706 and its associated components can in someembodiments analyze this operating information, such analysis caninclude comparison of the operating information with an operatingprotocol, calculation of a property of the operation of grow lightsystem 100, and/or identification of operating information to include ina report or notification; generate a report or notification regardingthe analysis of the operating information; and sending the report ornotification to a mobile device or server configured to be accessed byauthorized users.

As shown for example in FIGS. 7 and 8 the grow light system 100 can alsoinclude a number of additional devices that can affect the growingenvironment. These additional devices can include, for example, an airhumidity pump 752 which can be used to increase the humidity of the airin the growing environment; an external fan 754 which can be used toincrease air flow in the growing environment and also can be used todecrease humidity and change air conditions in the growing environment;a temperature adjustment mechanism 756 which can be used to raise orlower the temperature in the growing environment; a water pump 758 whichcan be used to deliver water to the growing environment and inhydroponic growing environments can be used to increase water flow inthe hydroponic environment; a carbon dioxide pump 760 which can be usedto pump carbon dioxide into the growing environment; and a nutrient pump762 which can be used to deliver nutrients such as fertilizer to thegrowing environment.

Light has three principal characteristics that affect plant growth:quantity, quality, and duration. Light quantity refers to the intensityor concentration of light. Light quality refers to the color orwavelength reaching the plant surface. Red and blue light generally havethe greatest effect on plant growth. Blue light is primarily responsiblefor vegetative growth or leaf growth. Red light when combined with bluelight, encourages flowering in plants. Light duration or photoperiodrefers to the amount of time that a plant is exposed to light within acertain amount of time (such 24 hours) and this can affect a plant'sability to flower. As stated above, the grow light system 100 caninclude a spectral light evaluation sensor 708. Based on the readings ofthe spectral light evaluation sensor 708, the grow light system 100,through the processor 702, can adjust certain lighting parameters suchas the intensity quantity, quality, and duration of the light beingemitted from the LEDs 206. For example, the grow light system 100 canturn on or off certain LEDs having a particular wavelength (i.e. bluelight, red light, green light, etc.) and/or increase or decrease theirintensity. In other embodiments the grow light system 100 can beprogrammed for a certain type of plant for which the ideal spectrallight schedule is known and the grow light system 100 can automaticallyadjust the LEDs based on the known schedule. In still other embodimentsthe user can manually adjust the LEDs 206 as required through the userinterface 112. In still other embodiments the grow light system 100 canmonitor ambient light levels and adjust to the ambient light conditions.For example the grow light system 100 can be used as supplementallighting. When ambient light levels are inadequate, for example during aperiod of inclement weather conditions, the grow light system 100 canturn on or increase the intensity of the LEDs 200.

Additionally, water is a primary component of plant growth. Watermaintains the turgor pressure or firmness of tissue and transportsnutrients throughout the plant. Water is present in multiple locationsin a growing environment such as the humidity in the air and themoisture in the soil. Proper plant growth can be affected by both thehumidity in the air and the moisture in the soil. Plant growth can beaffected by the timing and amount of water applied during production.Certain stages of plant growth are more sensitive to water stress thanothers. Based on the readings provided by sensors such as the airhumidity sensor 710, the soil moisture sensor 714, and in hydroponicgrowing environments, the water flow sensor 722 and the water levelsensor 724, the grow light system 100, through the processor 702, canadjust certain water levels. For example, if the air humidity sensor 710detects an air humidity that is too low for a particular growingenvironment, the I/O module can activate the air humidity pump 752 toincrease the air humidity. Similarly, for example, if the soil moisturesensor 714, water flow sensor 722, or water level sensor 724 detectwater levels that are too low, the water pump 758 can be activated toprovide water and/or water flow to the growing environment. As with allother adjustments, the user can manually adjust the air humidity pump752 and the water pump 758 as necessary through the user interface 112or other input.

Further, carbon dioxide is necessary for photosynthesis and propercarbon dioxide concentration through the course of the growing processcan allow for faster maturation and larger yield. For example, a carbondioxide level in the growing environment between 700 and 900 ppm canimprove crop development and yield. In some embodiments, the grow lightsystem 100 can include an air sensor 718 to determine the composition ofthe air in the growing environment including for example carbon dioxidelevels and oxygen levels. If, for example, the carbon dioxide levels aretoo low, the carbon dioxide pump 760 can be activated to provideadditional carbon dioxide to the growing environment.

Similarly, other sensors, such as pH sensor 716, the ambient airtemperature sensor 720, and the air flow sensor 712, measure growingenvironment qualities that are important to growing plants. The pHlevel, for example, is the measure of the acidity or alkalinity of asoil and can be important to a number of factors affecting plant growth.Ambient air temperature is also important to plant growth and can affectphotosynthesis, respiration, transpiration, flowering, and sugarstorage. Air flow is also important to plant growth. As described abovewith regard to other sensors, devices such as the nutrient pump 762 (toadd nutrients such as fertilizer to the growing environment),temperature adjustment mechanism 756 (to raise or lower the temperatureof the growing environment), and external fan 754 (to provide air flowin the growing environment) can be activated to optimize the growingenvironment based on information from the sensors 716, 720, and 712 orbased on user input from, for example, the user interface 112.
